Our take:  The DBoys M4 CQB-SD with a full metal body (full metal receiver, barrel, stock bar, and pistol grip) and a full metal gearbox is a value-minded, high-performance AEG.  It’s one of the best choices for an AEG because its lack of compromise between realism and power.  With a full metal body and realistic weight, as well as a full metal gearbox that shoots hard, it’s one of the best deals around because of its low price tag.  Comes also with a full metal built in RIS system for easy upgrades.

With a muzzle velocity that overpowers even Tokyo Marui AEGs, this M4 CUSTOM CQB-SD is ready to rock and roll.  Also features adjustable hop-up, adjustable rear sights, and a rear-retractable, 4-point crane stock for extra comfort.  With full Tokyo Marui parts compatibility and many other aftermarket upgrade parts compatibility, this AEG can be easily customized and upgraded.  The rail system further adds onto the upgrade potential of this gun, since you can add an almost endless amount of tactical accessories to it, including flashlights, scopes, lasers, and grenade launchers.

DBoys has done a terrific job in balancing power with realism, as this full metal M4 CQB-SD full auto AEG rifle from DBoys is one of the best M4s on the market at the absolute lowest price.  With an ultra high-torque motor installed directly from the manufacturer, this airsoft rifle cranks out over 800 rounds per minute on full auto mode and is sure to impress in the performance department.  Thanks to a full metal barrel, shots are accurate and crisp.

This fully customized FULL METAL M4 CQB-SD has been loaded to the gills with add-on accessories, including:

1. 415 FPS Airsoft DBoys Full Metal Quad Rail M4 CQB-SD AEG Rifle

Specifications:
Operation:  Electric Automatic
Build:  Full Metal Receiver, Barrel, SD-Style Silencer
Firing Modes:  Full-automatic and Semi-automatic, w/ Functional Safety
Muzzle Velocity: 380-415 FPS (w/ 0.20g Bbs)
Gearbox:  Full Metal Version 2
Magazine: 300rd High Capacity (gear wind-up)
Hop-up:  Adjustable
Weight:  8.5 pounds 
Color: BLACK
Ammo type:  Seamless 0.20g or heavier (0.23g, 0.25g, 0.26g,0.28g,etc) BBs.  For maximum performance and accuracy, Airsoft Megastorerecommends GoldenBall ProSlick BBs which carry perfect sphericalconsistency and density, available at Airsoft Megastore for the lowestprice on the market, guaranteed.

2. AMA Airsoft Rail Mounted Pressure Switch Red Laser

3. AIM Sports 90 Lumen Pressure Pad Flashlight w/ Quick-Release Mount

4. AMA 7-Intensity Airsoft 1x40 Red Dot Scope w/ Rail Mount

Package includes:  Rifle, rechargeable battery, wall charger, instruction manual, 300-round high capacity magazine, flashlight unit, premium metal red dot scope, foregrip, laser

Battery Charger Recommendation:  Although this fully automatic airsoft rifle comes with a standard wall charger to charge the battery, Airsoft Megastore recommends the use of a smart charger to avoid overcharging the battery (overcharged batteries may cause decreased airsoft gun performance and may shorten battery life significantly).  Smart chargers not only shorten charge time significantly (up to 800% faster charging), but more importantly, also automatically shut off once the battery is fully charged to avoid overcharged batteries.

5 420 FPS CUSTOM Airsoft DBoys Metal M4 CQB-SD AEG Rifle Package *****
Amazing gun

"The gun looks amazing. Its metal finish is legit. The silencer looks different then pictured here which is a good thing. The flashlight had to be taken apart to insert the batteries. The LED is bad. The scope is great. The fore-grip is great. At first my mag wouldn't click in right away. You have to insert it in a specific way to make it click in on the first try. At first I thought it was broken. The stock is Great, the battery goes inside the which gives nice balance to the gun. The rate of fire on Semi is great, the auto is equally amazing. After tweaking the red dot on the scope I'm able to hit within 1 inch of the target at 50 ft. even while squeezing off multiple rounds. I hit the same EXACT spot 10 times in a row. I shot the box it came in from 50-60 ft. and it went through the box. The accuracy and FPS are great and the gun itself is beautifully made. The accessories it comes with are rather cheap. I'll give the gun a 10/10 and the package a 8/10. "

My first airsoft rifle and the new love of my life!!!!

"The gun is very life like. It's full auto is one mean mother and it's semi auto is a gift from airsoft heaven. DBoys really know their stuff when it comes to these types of airsoft weapons especially the M4! I reccommend it to anyone who takes this game seriously! Hooyah!"

awesome! BEST AIRSOFT I EVER BOUGHT

"Pros - Price - Power - Outdoor range/CQB domination LOL - Nice weight to it, real beefy too - Gearbox is superb (had my local tech check it out, he couldn't believe it was a JG!) Cons - I only have 1 extra mag (need to get more) That's it! This thing is a great deal and a good performer on EVERY level, no matter what airsoft scenarios/games you're into - J. Henderson"

What a great deal/gun

"very pleased with the build quality and the sheer value of this package deal. I will be buying much more from Airsoft Megastore, as airsoft is booming in North Carolina! Great guns at the lowest prices you can find em for. Good stuff, too, that won't break the bank, especially in these tough times"

Great gun

"This gun is very reliable and comes with all the attachments but the scope, as usual, is a cheap version of the real thing that is good for night or indoor fights but the gun does come with iron sights. It is a little tough to get the battery in but after the first time you should get used to it. The gun also takes about 2 and a half hours to charge."

Very good but watch out

"This is a very good gun but watch out it came with all the upgrades as said,but the laser pointer was very fragel and broke the wire got disconnected. so if u buy this product make sure to charge it alot and dont mess up the attachments. The fire rate on it is very beasty and its fps is freaken awesome so yay buy this gun but watch out!(FOR Mark Volgler in TX) and Mark Volgler i would say get the gun, the silencer does look different when u pull the gun out and so does the flashlight. and whats on the left side is a laser pointer. but do NOT use .12 bbs use .20-.25, my gun jammed when i used .12 bbs, then i used .25. and any grenade launcher would fit becuase it has a full metel railing system and its length is HUGE!!!! so i would recomend this gun, i just went to a war with it and it shot so far so it does have 400+ fps depending on what bullets u use."

love my gun

"this is the first gun i ever bought and i could say im happy i bought it. Like justin i had the same problem with my hop-up, i would try adjusting it and it wouldn't do anything. Luckily my cousin fixed the problem for me. overall this is a great gun for beginners, don't expect anything too fancy for the price you're paying. The flashlight is plastic and my scope came broken but airsoftmegastore took care of everything for me. they have great customer service, thanks airsoftmegastore! fyi i put a tight bore barrel and im not shooting 370fps with .2's"

Just arrived

"Battery. You need to remove the rubber at the back of the butt, and remove a screw to get the battery compartment open. The hop up is located in a little door that opens up when you pull back the cocking mech. The white wheel adjust the hop up. ROF is a bit less than I hoped for. It is around 700. My son's ak is about 20% faster. Power: Very strong. 360-380FPS easy. Recommend .23 or .25 bbs. .20 are all over the place. Accuracy. Disappointing. after adjusting the hop up, it was better but it still shoots pretty wild. At 150 Feet the about 20-30% of bbs go right and left by about 4-5 feet. It looks like you are spraying the target. Build quality. Excellent. Very heavy 9lbs. the butt is a bit loose but everything else heavy metal and tight. The red dot sight it came with is awesome. very high quality. The silencer is just for show, the gun is very loud. Overall a great feeling and looking gun if accurate target shooting is not your thing. "

Good Gun

" good gun. For the attachments... the scope is awesome, the flashlight is alot different from on the picture but it is still good, The laser sucks. the fore grip is great. buy bbs heavier then .2, .2 for me get jammed alot and they tend to curve alot after about 20 ft. some differences with the foto is that the mock surpressor isnt colored like that at the end, a little plastic piece comes out and is colored orange. also the flashlght is longer and has more of a normal shape. it still fits fine on the bottom with the fore grip. also the gun is alot darker all aroung. all of it is straight up black. the surpressor is not as long as showed. the mags are hard to click in you have to wiggle them a bit till you feel it go in. OVERALL: Fps, not sure precisely, but it is pretty good out of the box. rps: pretty good as well. also you have to be patient w/ this gun to figure out how it work and how to use it properly. I would not reccomend it as someone's first AEG"

I love the pro gunbuilder by golden eagle!
The gunbuilder was very useful and made it easy for me to buy my first mid/high spec gun for just about $300. It gave me comfort in that i can get more parts to switch out at a later time if i wish to change anything about my rifle and that there will be compatible parts for any modifications i choose to do on it. The gun came in full working order and the hopup was even adjusted to be perfect right out of the box. I could easily hit targets over 150ft away constantly. Johnmstopka, USA
